Will the owner know the information after Xiaomi 10 swipes the machine?

No, the owner won't know the information after Xiaomi 10 is finished.

Mobile phones don't send SMS reminders. If you turn on my mobile phone and turn on the lost mode, contact information will appear.

However, the anti-loss mode is useless after the phone is swiped, and the Android phone will not send a notification message, so the owner will not know the information after the phone is swiped by Xiaomi 10.
